The will of former New York Mayor Ed Koch was filed on March 11, 2013 in the New York Surrogate's Court. In his will, Mayor Koch left $100,000 to the LaGuardia and Wagner Education Fund at CUNY. Mayor Koch was remembered as someone who loved films and who believed that students should start thinking about careers and public service. It was his hope that the $100,000 will be used to host a series of student-made videos about the subject.

At the time of his death, Mayor Koch's estate was valued between $10.5 and 11 million. Most of his estate was left to his surviving family members. Besides the school, he also left a small bequest of $100,000 to Mary Garrigan, his longtime secretary. He had also collected a number of photographs of himself with various ambassadors, U.S. presidents, and even the late-Pope John Paul II. He donated the collection to the New York Historical Society. According to the Wall Street Journal, "Mr. Koch left $500,000 to his sister Pat Thaler, the will's executor, and $50,000 each to Gail Koch, his late brother's wife; Andrew Koch, his nephew; and Joey Koch, his niece. The remainder will be distributed to Ms. Thaler and her sons, said Mr. Kriss.
